The moving frames 131, 131 'are connected to the pair of switches 136,
When the position is detected by 137, the operation is stopped, and when the detection switch 136 for the forward position is operated, the reversing operation is performed after the operation is stopped, and the carrier 50 is carried in from the receiving port 11 to press the moving frame. When the start switch 138 is positioned in front of the piece 133,
31 and 131 'are driven to move forward.

The fluid cylinder 135 is, as described above,
While pressing the pressing piece 133 with a predetermined pressure, the pressing piece 13
When the pressure in the retreating direction applied to the pressure piece 3 is equal to or greater than the pressure on the pressing piece 133, and thus when the pressing piece 133 is retreated, a detecting means 135 'for detecting the retreating operation of the pressing piece 133, for example, a pressure switch When the detecting means detects the retreating operation of the pressing piece 133, the moving frames 131 and 131 'are stopped from moving forward and the reversing retreating operation is performed.

The tip of the pressing piece 133 has a rotating end 1.
33 ', and the rotating end 133' is
31 and 131 'can rotate in the forward direction, but cannot rotate in the backward direction.
When the carrier 50 relatively moves under the pressing piece 133 in the forward direction, the passage is permitted, and when the carrier 50 is located in front of the pressing piece 133, the moving frames 131, 131 'move forward. The pressing piece 133 is configured to press both ends of the carrier 50.

As shown in FIG. 6, the carrier 50 has a rod-shaped support 52 having bumpers 51, 51 'at both ends.
A holding frame 53 is provided so that the transported object 40 is mounted on the holding frame 53. Wheel mechanisms 54, 5 provided at both ends are provided.
The transfer guides 14 and 14 'are formed so as to be engaged with the transfer guides 14 and 14'. In the embodiment, the transfer guides 14 and 14 'are formed by guide rails.

Further, a stopper mechanism 16 for sending out one transfer object 40 is provided on the side of the delivery port 12 of the device 10 of the present invention. As shown in FIG.
The first for locking the leading carrier 50 at a predetermined position
And the second locking piece 162 that alternates with the first locking piece 161. The first locking piece 161 stops the leading carrier 50. When the first locking piece 161 releases the leading carrier 50, the second carrier 50 'that comes into contact with the first carrier 50' is disengaged from the second carrier 50 '. 2
Are configured to be locked by the locking pieces 162. Thus, for such a stopper mechanism 16, a conventionally known configuration may be selectively used.

Since the apparatus of the present invention is like this, when the first carrier 50 is supplied from the receiving port 11 and is carried in front of the pressing piece 133, the carrier 50 is moved to the movable frames 131 and 131 '. With the synchronized movement, the pressing piece 13
3 and is moved until it is locked to the first locking piece 161 of the stopper mechanism 16 as shown in FIG. The moving frames 131, 131 '
In the forward position shown by the solid line on the right side of FIG.
36, the moving frames 131, 13
As shown by the chain line on the left side in FIG. 3, 1 'retreats to the receiving port 11 side until the position is detected by the switch 137, and stops at this position. During the retreat of the moving frames 131, 131 ', a second carrier 50' is carried into the apparatus from the receiving port 11, and this carrier 50 'is located below the pressing piece 133 after the retreat of the moving frames 131, 131' is stopped. And is extruded forward. At this time, the rotating end 133 'of the pressing piece 133 is rotated upward while being lifted up by the carrier 50' as shown by the dotted line and retreats above the carrier 50 ', and after passing through the carrier 50', it is suspended and restored at the rear position. . When the carrier 50 'reaches a predetermined position, the start switch 13
8 operates by detecting the carrier 50 ', whereby the moving frames 131, 131' resume moving forward, and the second
The second carrier 50 'is a rotating end 133' of the pressing piece 133.
As shown in FIG. 1, at the time of contact with the first carrier 50, the forward movement is stopped and stopped. At this time, a pressure in the retreating direction acts on the pressing piece 133, and when this pressure increases to the extent that the piston of the fluid cylinder 135 is retreated, the cylinder detecting means 1
35 'operates, and the moving frames 131 and 131' move backward.

Each time the moving frames 131, 131 'move backward, the subsequent carriers 50n, 50n2,... 50nx are sequentially supplied from the receiving port 11, and the carriers 50n2,.
0nx is sequentially transferred to the outlet 12 side by the pressing piece 133 and stored as shown in FIG. Thus, the moving frames 131 and 13
Since 1 'moves backward by detecting the pressure of the fluid cylinder 135, regardless of the number of carriers 50... 50nX stored, the last stored carrier is pressed with a uniform force and then returned. Next, in the second step 30, when the processing of the preceding transferred object 40 is completed, the carrying-in means 31 of the second step 30 operates to receive the stored carrier 50, and accordingly, the first engagement of the stopper mechanism 16 is performed. Stop piece 161
4 retracts from the solid line position in FIG. 4 to the chain line position to release the leading carrier 50, and at the same time, the second locking piece 162 advances from the solid line position in FIG.
Lock 0 '. Therefore, the loading means 31 can receive only the leading carrier 50 and transport it to the painting booth 32. When the leading carrier 50 is sent out, the first locking piece 1
61 and the second locking piece 162 return to their original positions indicated by solid lines, respectively, so that the subsequent storage carrier is pressed by the last carrier to be transferred next and moves forward collectively, and the carrier located secondly 50 'is the first locking piece 1 as the leading carrier.
Locked to 61. In this way, the carriers sequentially sent from the first step 20 are stored in the apparatus of the present invention, and the carriers are sequentially loaded into the second step 30, so that the first step 20 and the second step Even if the processing time with the process 30 is slow, this slow speed can be absorbed by the storage operation, and the process of the second process 30 can be performed smoothly.

In the above process, the device of the present invention can be configured as follows. In the device of the present invention, the detection means 135 'of the fluid cylinder 135 is operated by the pressure acting on the pressing piece 133 with the first locking piece 161 of the stopper mechanism 16 as a fulcrum, whereby the moving frames 131, 131' are retracted. Therefore, the switch 136 for detecting the front position of the moving frames 131 and 131 'may be omitted in some cases. The moving frames 131 and 131 'may be configured to retreat after passing through the next carrier 50' which has been previously loaded into the apparatus. In this case, the rotating end 133 'of the pressing piece 133 is the carrier. When passing through the carrier 50 ', the carrier turns upward while climbing over the carrier 50'. In this case, since the moving frames 131 and 131 'are restarted to advance regardless of the carrying-in timing of the carrier 50' or the existence of the carrier 50 ', the start switch 138 is unnecessary, and the moving frame 13 is not required.
1, 131 'can be configured to be stopped at the rear position by the rear position detection switch 137 and to move forward repeatedly. The transfer guides 14, 14 'are
In addition to the configuration of hanging the carrier 50 like a guide rail,
A ball conveyer on which the carrier 50 is mounted may be used. In this case, it is desirable that a sliding plate be attached to the lower surface of the carrier 50 to improve the sliding property.

[0016]

Since the device of the present invention is as described above, the carrier 50 is pushed forward by the pushing pieces 133 of the pair of moving frames 131 and 131 'operating in synchronization with both ends thereof, and is advanced. Since the fluid cylinder 135 presses and contacts the first locking piece 161 or the preceding carrier with a predetermined pressure, both ends of the carrier 50 are accurately regulated at right angles to the traveling direction. There is an effect that it can be delivered to the carrying-in means 31 in the two steps 30.
